About this game

Before the nightmare began, there was the experiment inside a mysterious hotel.

This game is not that bad, but seriously, Hari running for only 7 seconds and then you need to wait to recharge your stamina in like 3 or 4 minutes. Also, about the Lord, he runs like super fast and when I play easy mode, but my stamina is empty, he runs like in the old normal mode (in 1.0.2/1.0.3) but a bit too fast, and catches me. But when I play normal mode, I try to run away from him when I'm running (with the Luka-Cola power) but he immediately catches me because I only ran for 3-4 seconds

We are sorry to see you are having problems! The performance of the game is a priority for us and something we will continue to optimize. Maybe we will add more time to run for next update!

This game is good but there's a bug in chapter 3, for some reason the textures in chapter 3 is completely pitch black but not the map itself. The items textures, including The Hunter's model and even Hari's hand and arms (when I activate the running button) is all pitch black. It makes it difficult to see in chapter 3 so please fix this. Edit: There's another issue when I complete chapter 3, chapter 4 is still locked and it won't let me watch an ad to unlock it and I'm connected to the internet.

Games fine til I get to an item needed. Once I'm hovering over it waiting on the action button to respond and pop up suddenly the controls go haywire and no matter the sen. Setting or how many ways I try, it glitches then jumps and won't work together to get close enuff to grab. Goes for normal to then it's like I'm drunk& can't control my neck w/the screen wippin around, glitching, freezing& jerking. Step back, goes normal again til I approach what I need.&not saving progress @all is insane.
